The Toyota 3.4L V-6 is a good engine in its own right, but a TRD supercharger pumps up the performance and the fun factor. An Underdog Racing Development (URD) drive pulley is slightly smaller than standard, increasing boost pressure and therefore power output. Note the smog equipment and factory fuse box, which have built-in mounts on the rollcage. An AEM computer controls the EFI system and was tuned to perfection by DynoTech in Vista, California.
